Randomly-selected participants will then watch a tutorial on descending devices, complete an initial evaluation, and test a descending device during the trial period from July 1, through Sept. 30, 2017.

When the trial period ends, participants must complete a detailed post-evaluation about their experience.

Preliminary results of the evaluation will be available in late 2017.
